Defining the Observer:A General Physical Criterion, Its Relation to Existing Models, Impossibility of the final ascent, and the Impossibility of the Ideal Limit. No treatment of quantum gravity that takes observers seriously can avoid the question of what an observer physically is, and existing treatments - including the author's own (Materov 2026a,b,c) - each state a modelling assumption for the observer without deriving it. This paper's contribution is narrow and specific, not a claim to be the first physical account of an observer: a particular combination of requirements (D1–D4) on the trajectory of an embedded tensor factor, a separately-argued self-capacity criterion for individuation (D3′) tied to the no-cloning theorem, and a short, self-contained no-go argument (Proposition 4.1) for complete reconstruction of an observer's complement. We show that the observer-notions already in use in Materov (2026a,b,c) relate to this combination in three structurally different ways - as a more general object, as a concrete realization, and as a structurally parallel system not yet unified with it - and work out one concrete case, the photonic Friend of Local-Friendliness experiments, in detail. Since no observer can be ideal in this omniscient sense, we instead investigate uniqueness for a weaker, separately-defined notion (a self-dominant observer, whose own representational capacity exceeds its observing capacity); no dimension-counting argument we have found forces this either, and the question remains, honestly, open.

This paper reconstructs the concept of observation from first principles rather than treating it as a primitive notion. Starting from the existence of meaning, a unique structural dependency chain is derived: Meaning → Being → Subject → Other → Distinction → Comparison → Order → Time → Update → Self-Reference → Observation → Record → Synchronization → Information Each stage is proven to be a necessary prerequisite for every subsequent stage. Within this framework, observation is shown not to create or determine reality. Instead, reality must already exist before observation becomes possible. Observation is defined as a structural operation performed on an already existing reality. The paper further applies this structural derivation to the observer problem, Schrödinger's cat, Wigner's friend, and the double-slit experiment. It argues that the disappearance of interference should be interpreted as the consequence of changes in physical interaction together with the subsequent processes of recording and synchronization, rather than evidence that observation itself creates or modifies reality. This work provides a mathematical reconstruction of observation prior to information and proposes a unified structural framework for interpreting quantum measurement from more fundamental principles.
This paper reconstructs the historically polysemous “Copenhagen interpretation” not as a specific ontology, but as a minimal axiomatic system that specifies the conditions under which candidates, observations, and records are established. In a previous paper, the EPR paradox was reconsidered through a type separation between prediction and observation, leading to the Prediction–Observation Separation Principle and the Ontology Non-Generation Principle, which prevent a probability-one prediction from automatically generating the reality of an unobserved object. In another paper, this observational framework was extended to temporal and causal constructions, yielding the Temporal Extension of the Copenhagen Interpretation (TEC), in which a single causal record is established from unrealized causal candidates. The present paper reorganizes these two arguments from the perspective of a higher-level axiomatic structure.First, I introduce a framework of typed existence in which objects and propositions meaningful within a theory possess a minimal “existential attachment,” while that existence does not immediately imply physical reality. When reality is asserted, one must specify what type of reality is being claimed and what authorizes promotion to that type. In this way, inferences that move from observational or predictive formalisms to realism without warrant can be treated as type errors. I then organize candidatehood, observation, single records, ontological suspension, prediction–observation separation, and record stability into a minimal Copenhagen axiomatic system.When this axiomatic system is applied to time, the past can be constructed as established records, the present as the local boundary at which candidates become records, and the future as unrealized causal candidates. This yields a distinction between “realized record time” and “model time” constructed by general relativity or cosmology. General relativity can then be repositioned as an advanced model theory that constructs smooth spacetime geometry and temporal scales from realized time. If the map back from that model to observational records preserves structure, it provides a condition for integrating Copenhagen observation theory with general relativity at the level of time and causality. Furthermore, by defining continuous observation as record formation over real-valued time and asking whether such a process is physically realizable, the question of time quantization is shifted from an a priori assumption to a problem of deciding the possibility of continuous observation.Finally, part of the difficulty of quantum gravity is reinterpreted as arising from implicit conversions among different time types, existence types, and causal types, together with circular dependencies among them. Quantum gravity is not merely the problem of quantizing a completed theory of general relativity; it is also the problem of making explicit the interfaces among theories so that realized time can be constructed from observational records and relativistic model time can then be reconstructed from it. This paper therefore positions the proposed reconstruction not as a completed theory of quantum gravity, but as an axiomatic and semantic refactoring required at a prior stage.

This work addresses the long-standing claim that interference phenomena—most notably in double-slit–type experiments—cannot be physically modeled without invoking wave propagation or particles following multiple trajectories. We show that this claim rests on an implicit restriction to local, dynamical descriptions acting between emission and detection. We introduce a minimal framework in which detection events are treated as discrete realizations occurring at an absorbing boundary, while the observed interference pattern arises from global structural admissibility constraints of the full experimental configuration. The model does not attempt to generate or predict individual detection events. Instead, it characterizes the statistical distribution of outcomes as a property of realization closure rather than of local evolution in transit. Within this approach, interference patterns are understood as emergent statistical signatures of global realization structure, not as evidence of propagating waves, hidden variables, or oscillatory dynamics in space. The framework preserves all empirical features of standard interference experiments while avoiding assumptions about intermediate physical processes that are neither observed nor required by theory. This work is consistent with relativistic and quantum no-go results concerning photon trajectories, localization, and in-flight observables. It complements earlier structural interpretations of light and realization by providing a concrete, physically explicit model demonstrating how stable interference statistics arise without propagation. The contribution clarifies the precise sense in which interference is modelable, and the sense in which it is not: individual events remain intrinsically unpredictable, while their global organization is physically intelligible at the level of realization structure. The model introduces no new forces, fields, or modifications of established equations, and is intended as a refinement of conceptual foundations rather than a replacement of existing formalisms.
Quantum theory (QT) treats of “observables” yet the term “observer” remains hardly a rigorous notion. We argue that the uncertainty principle of QT can be understood in the Godel sense that: any given observer constitutes own practical definition of “the unobservable” (if superposition) namely length scale, phase space, non-local action, fundamental frequency etc. Conversely, the observable is definable strictly only in inverse-observer terms as, that is, the “collapse” namely inverse-length, phase-points, locality, harmonics respectively. Granted this picture is not a-priori intuitive we show that it resolves key modern difficulties plus it has formal grounds. One pictures the observer thus in the manner of Godel’s “consistency-is-undecidable” or Planck’s “the-constant-is-uncertainty” or indeed Einstein’s “speed-of-light-is-null-information” etc. definitive of which three cases, we assert, is Peano’s (and Noether’s?) notion of the constant as being for any gamut of variables/symmetry the meta-state (“conserved current”?). Given then that the observer is in any scheme of events the invariance (constant) it should be the case that it is the observer proper and not his observables which should constitute the violation of Bell’s inequality—if as the infinitesimal/imaginary axis or as the dimensionless/infinite-dimensional or the so-called conservation law etc. We posit: the observer is by definition the virtual exchange (field) of standard model or “space-time” of GR or just the “metric”—defined by the singular trait that it is the de facto universal constant i.e. the natural unit and hence natural limit of physical information. As a prediction we show herein an exact value to define man (perhaps our purest sample of observer) as also the natural unit for quantum gravity. Ultimately, that known hitherto as the potential (conservation law) becomes here same exactly as the “mind” or the “life” i.e. strictly put: “the-observer-as-the-unobservable” (superposition).The observer is for us per se the “entity”—in the sense of “phase-space” (normal mode; fundamental; wave speed) giving us an intuitive picture of observables that is same in fact as Huygens’ wave fronts/wavelets (or Everett’s many-worlds, or indeed Darwin’s evolution/speciation of “life”) same in short as any “spontaneous symmetry breaking”.
